1. A body fluid meter assembly, comprising:
a body fluid collection container configured to collect body fluid;
a body fluid meter unit comprising a load cell and a coupling mechanism configured to releasably couple the body fluid collection container directly to the load cell, which body fluid meter unit is configured to process sensor data supplied by the load cell and derive a measurement of a quantity and/or flow rate of the body fluid accumulating in the body fluid collection container as a function of load applied on the load cell; and
tubing attached to an inlet port of the body fluid collection container and configured to be connected to a source of the body fluid,
wherein the body fluid collection container is a rigid container and wherein the coupling mechanism is a spring-loaded interlocking mechanism configured to cooperate with one or more interlocking members provided on the body fluid collection container and interlock with the body fluid collection container to form a connection between the body fluid meter unit and the body fluid collection container,
wherein the spring-loaded interlocking mechanism comprises at least one spring-loaded release lever comprising a locking portion configured to cooperate with a locking section provided on a corresponding one of the one or more interlocking members, and
wherein each spring-loaded release lever is supported so as to pivot between a first position in which the locking portion of the spring-loaded release lever engages with the locking section of the corresponding interlocking member and prevents disengagement of the body fluid collection container and a second position in which the locking portion of the spring-loaded release lever is disengaged from the locking section of the corresponding interlocking member and allows disengagement of the body fluid collection container.
